Rostock is the largest city in the north German state Mecklenburg-Vorpommern. Rostock is on the Warnow river; the quarter of Warnemünde 12 kilometres (7 miles) north of the city centre is directly at the coast of the Baltic Sea.
Rostock is home to one of the oldest universities in the world, the University of Rostock, founded in 1419.
The city territory of Rostock stretches for about 20 km (12 mi) along the Warnow to the Baltic Sea. The largest built-up area of Rostock is on the western side of the river. The eastern part of its territory is dominated by industrial estates and the forested Rostock Heath. Rostock is considered a regiopolis and is favourably located within the metropolitan regions of Hamburg, Berlin, Copenhagen-Malmö and Stettin and is close to the equally sized city of Lübeck.
